Panasonic announced the forthcoming availability of the advanced AJ-HDP2000 2K Processor. Available by late summer, the 2K processor allows professionals to record and process pristine quality 2K and HD images to D-5 VTRs for editing, interchange and distribution.
Designed specifically for use with telecine systems and especially within the rapidly growing DI workplace, the AJ-HDP2000 processor uses JPEG2000 compression, the same compression scheme specified by the Digital Cinema Initiative (DCI) for cinema release. The AJ-HDP2000 processor accepts 12-bit 4:4:4 "2K" 2048 x 1080 resolution film image data, or 12-bit 4:4:4 sampled 1920 x 1080 HD images, and records to the AJ-HD3700H, AJ-HD3700A and
AJ-HD3700B D-5 HD VTRs for editing, archiving and distribution. Using the advanced compression algorithm, film can be converted to digital data for subsequent processing in advanced DI environments.
The AJ-HDP2000's JPEG2000 wavelet-based compression format ensures that images remain faithful throughout the recording process, and are never subjected to potentially visible dct block based artifacts
. The advanced encoding minimizes distortion and resolution degradation and offers optimized bit rate control and increased error tolerance for reliable interchange required in editing. For ease of monitoring and interfacing with more traditional high definition equipment, Panasonic has added a 4:4:4 to 4:2:2 conversion capability.
Post facilities using D-5 will be able to use their current HD3700s, and the workflow that has worked so well for them with existing D-5 HD VTRs can be continued with a simple software upgrade for 2K and HD post-production.
The full audio capability of the D-5 format is maintained, including eight-channel 24-bit recordings, as well as the ability of the system to handle compression audio streams for multi-channel / second language applications. Audio I/O is by means of embedded HD-SDI or AES/EBU inputs. Interconnection from the processor to the D-5 VTR is by mapped compressed data over the D-5's existing HD-SDI input / outputs. The processor accepts dual link SMPTE 372 video / 2K inputs. Time Code in/out is embedded or XLR. Maximum record time is 155 minutes at 24fps HD / 2K modes.
The AJ-HDP2000 will be available in August 2007 at a suggested list price of $35,000.
